Of course going up the Vandy line will yield better reproduction, but I think the OP wanted to ugrade sound quality for his networked system.
I, too, have been working on this.
Just last week I bought Fidelizer and have been wowed by the difference in my system. Since you are using a Mac, I am sure there are other programs that do the same thing (optimize OS for music reproduction).
A quick Google brought up something called Museeks. I don't run Mac, so I can't say if it is good or not, but maybe worth a try.
